Is Sealing a Cedar Fence Necessary?
Before we show you how to seal a cedar fence, let’s answer another important question: do you have to seal cedar fences? Here’s what you need to know about sealing cedar fences, and why it’s so important for a beautiful fence that stands the test of time.
Do You Have to Seal Cedar Fence Boards?
Do you have to seal cedar fences? Does cedar fencing need to be treated? Technically, no.
Cedar can naturally withstand the elements without much deterioration. The wood's natural oils help it resist rot, decay, and insect damage, making it a popular choice for outdoor fencing.
However, this doesn’t mean that cedar is impervious to the effects of weather and time.
Long-term exposure to sunlight, rain, and temperature fluctuations can cause the wood to gray, warp, or crack. A cedar fence seal can help mitigate these effects and keep your fence looking its best.
Should You Seal a Cedar Fence, Though?
Even though sealing a cedar fence isn’t a requirement, many homeowners choose to do so for the added benefits. So, should you seal a cedar fence? Here’s a look at the pros and cons of using a cedar fence seal:
Pros:
Sealing a cedar fence provides an extra layer of protection against the elements, helping to prevent moisture infiltration, warping, and cracking. This can significantly extend your cedar fence lifespan, saving money on repairs and replacing fence boards.
Unsealed cedar naturally weathers to a silver-gray patina over time. While some people find this look appealing, others prefer the rich, warm tones of freshly cut cedar. Sealing helps preserve the original color of the wood, maintaining its aesthetic appeal.
A good cedar fence sealer can prevent the wood from absorbing stains from dirt, leaves, and other debris, keeping the fence looking clean and fresh. Your beautiful cedar fence will look newer and stay stain-free for longer if it’s sealed.
Cons:
Sealing a cedar fence is not a one-time job. To maintain the protective benefits and the wood's appearance, you'll need to reapply the sealant every couple of years, which requires time and effort, not to mention the expense of quality cedar fence sealer.
And speaking of the cost, it’s not just the cedar fence seal you’ll have to pay for. You’ll need to invest in brushes or sprayers, or potentially professional labor if you choose not to do it yourself. For large fences, this can quickly add up.
What to Seal Cedar Fence With: Tips on Choosing the Best Seal for Cedar Fence
If you do decide that sealing cedar fence is the right choice for you, you’ll need to start with good quality products. So, what’s the best seal for cedar fence boards? Let’s talk about what to seal cedar fences with.
Types of Sealants
When it comes to sealing cedar fences, you have several options, each offering different levels of protection and finish. The main types of sealants are:
Clear sealants: These are ideal if you want to preserve the original hue of the cedar while protecting it from moisture, UV rays, and mildew. However, they may need to be reapplied more frequently than tinted options.
Tinted sealants: Tinted or semi-transparent sealants offer the same protective benefits as clear sealants but with the added advantage of enhancing the wood’s natural color or adding a slight tint.
Solid stains: While not technically a sealant, solid stains provide the most coverage and color, often hiding much of the wood’s natural grain. They offer strong protection against the elements but may require more maintenance, as they can peel or chip over time.
Cedar fence seal comes in both water-based and oil-based formulas. Water-based sealants are easier to clean up, dry faster, and are more environmentally friendly, but, oil-based sealants penetrate deeper into the wood, providing longer-lasting protection and richer color.
What to Look for in a Cedar Fence Seal
Cedar fences are often exposed to direct sunlight, which can cause the wood to fade and break down over time. Look for a sealant that offers strong UV protection to preserve the wood’s color and structural integrity.
Moisture is a major threat to the longevity of any wood fence. Ensure the sealant you choose provides robust water resistance to prevent warping, cracking, and rot. In humid climates, a sealant with added mildew inhibitors can help keep your fence looking clean and fresh.
Consider the ease of applying the sealant. Some products can be applied with a brush, roller, or sprayer, while others might require specific tools or techniques. Also, take note of the drying time and the number of coats required - this affects both your time and financial costs.
Finally, different sealants have varying lifespans. Some may need to be reapplied annually, while others can last several years. A longer-lasting sealant might cost more upfront but can save you time and effort in the long run.

How to Seal a Cedar Fence: Step-by-Step Guide to the Best Way to Seal Cedar Fence Boards
Sealing cedar fence boards is a pretty straightforward process, but one that can help you get many more years out of your fence. Here are step-by-step instructions on how to seal a cedar fence, and when to seal cedar fence boards.
When to Seal Cedar Fence Boards
Timing is crucial when sealing a cedar fence. The best time to seal your fence is when the wood is clean, dry, and free of any previous finishes or treatments. Ideally, you should seal the fence in mild, dry weather to allow the sealant to adhere properly and cure effectively.
Avoid sealing on extremely hot, cold, or humid days, as it can affect the application and drying process. In terms of when to stain new cedar fence boards, give your wood time to weather for at least a few months to ensure any residual moisture or natural oils have dissipated.
Cleaning the Fence Before Application
Before applying sealant, it’s essential to clean your fence first. Use a broom or leaf blower to remove leaves, dirt, and other debris from the surface of the fence, then use a garden hose or pressure washer to wash the fence.
For a more thorough cleaning, you can use a mild detergent mixed with water. Scrub the surface with a brush to remove any grime or mildew. Be cautious not to use too much pressure, as this can damage the wood.
After washing, rinse the fence thoroughly to remove any soap residue. Allow the fence to dry completely before applying the sealant. Depending on the weather, this could take 24 to 48 hours.
Applying the Sealant
Once the fence is clean and dry, you can begin applying the sealant. Depending on the sealant you’ve chosen, you can apply it with a brush, roller, or sprayer. A brush is ideal for small areas and detailed work, while a roller or sprayer can cover larger areas more quickly.
Before application, stir the sealant thoroughly to ensure an even consistency. Follow the manufacturer’s instructions for any specific preparation. Start at one end of the fence and work your way to the other, applying the sealant evenly.
For a brush or roller, work in the direction of the wood grain to ensure even coverage. If using a sprayer, apply the sealant in overlapping strokes to avoid streaks. Apply the sealant in thin, even coats. Over-applying can lead to drips and uneven finishes.
Curing Time
After application, allow the sealant to cure properly to achieve the best results. The curing time can vary depending on the sealant type and weather conditions. Generally, most sealants require 24 to 48 hours to dry completely.
During this time, avoid any contact with the fence to ensure the sealant sets properly. Check the manufacturer’s recommendations for specific curing times and any additional care instructions.
Post-Sealing Maintenance
Once the sealant has dried and cured, you’re done! Periodically check your fence for signs of wear or damage. Look for areas where the sealant may be wearing off or where moisture may be getting through.
Wash your fence occasionally to remove any dirt or debris. Avoid using harsh chemicals that could damage the sealant. Depending on the type of sealant you’ve used, you may need to reapply the sealant every few years. Follow the manufacturer’s guidelines for specific instructions.
